A line passes through the points (2, –2) and (–6, 2). The point (a, –4) is also on the line. What is the value of a?
Answer:
The value of a=6[/tex]
Step-by-step explanation:
step 1:-
col linearity of three points :-
We know that slopes of two parallel lines are equal.If two lines having the same slope pass through a common point ,then two lines will coincide . Hence ,If A,B,C are three points in the X Y- plane, then they will lie on a line,
that is three points are col linear if and only if Slope of AB= slope of BC
step 2:-
Since the given three points are col-linear, we have
Slope of AB= slope of BC
given points are A(2,-2) ,B(-6,2) and C(a,-4)
Step 3 :-
Slope of AB= slope of BC
[tex]\frac{2-(-2)}{-6-2} =\frac{-4-2}{a+6}[/tex]
[tex]\frac{-1}{2} =\frac{-6}{a+6}
by cross multiplication
we get \\a+6=12\\

what is the greatest common factor for 5 4 and 2
When referring to the normal probability distribution, there is not just one; there is a "family" of normal probability distributions?
Final answer:
There is a family of normal probability distributions, each representing different populations or sets of data with varying mean and standard deviation values.
Explanation:
Yes, there is a family of normal probability distributions. The normal distribution is a continuous probability distribution that can take on different forms depending on the mean and standard deviation. The family of normal distributions is characterized by different mean and standard deviation values, which result in different shapes of the distribution curve.
For example, the standard normal distribution has a mean of 0 and a standard deviation of 1, and its curve is symmetrical around the mean. Other normal distributions may have different means and standard deviations, resulting in curves that are shifted or stretched.
Each normal distribution in the family represents a different population or set of data, and knowing the specific mean and standard deviation allows us to calculate probabilities and make statistical inferences.

Sean Matthews is a waiter at the Duluxe Lounge. In his first weekly pay in March, he earned $300.00 for the 40 hours he worked. In addition, he reports his tips for February to his employer ($500.00), and the employer withholds the appropriate taxes for the tips from this first pay in March.
Sean Matthews' weekly earnings are subject to payroll taxes, including his tips. The deductions for social security and medicare are split between him and his employer. Understanding how these deductions work can enable him to maximize his total earnings.
Explanation:The subject of the question pertains to Sean Matthews' earnings at the Duluxe Lounge, which involves payroll taxes on his wages and tips. From his regular wages of $300.00 for 40 hours, "payroll taxes" of 6.2% for Social Security and 1.45% for Medicare are deducted. The same deductions also apply to his reported tips of $500.00. These deductions are shared between Sean and his employer, though, it's possible that the employer's share might effectively be passed onto Sean in the form of lower wages.

Net pay is the money you have left when your paycheck makes its way to you and all of the required taxes are taken out. To find Sean's net pay, both his earned wages and the reported tips will be considered for tax deductions.
Calculate total earnings for the week:
Wages = $300.00.
Total earnings = Wages + Tips = $300.00 + $500.00 = $800.00.
Assume a tax rate (federal, state, and other taxes) of 2%
Tax deductions = $800.00 x 2% = $16.00.
Calculate net pay:
Net pay = Total earnings - Tax deductions = $800.00 - $16.00 = $736.00.

A line has a slope of mc013-1.jpg and passes through the point (–5, 4). Which is the equation of the line?
Answer:
y = [tex]\frac{-3x}{4}[/tex] + [tex]\frac{1}{4}[/tex].
Step-by-step explanation:
Given : Graph of slope [tex]\frac{-3}{4}[/tex] and passes through the point (–5, 4).
To find : Which is the equation of the line.
Solution : we have given that point ( -5 ,4)
By equation of line ([tex]y-y_{1}) = m (x -x_{1})[/tex]
y - 4 = [tex]\frac{-3}{4}[/tex]( x +5).
y - 4 = [tex]\frac{-3x}{4}[/tex] +[tex]\frac{-15}{4}[/tex].
On adding 4 both sides we get,
y = [tex]\frac{-3x}{4}[/tex] + [tex]\frac{-15}{4}+4[/tex].
y = [tex]\frac{-3x}{4}[/tex] + [tex]\frac{-15 +16}{4}[/tex].
y = [tex]\frac{-3x}{4}[/tex] + [tex]\frac{1}{4}[/tex].
Therefore, y = [tex]\frac{-3x}{4}[/tex] + [tex]\frac{1}{4}[/tex].

[tex]m=\frac{-6}{8}[/tex]
[tex]m=-\frac{3}{4}[/tex]
Step 2
Find the slope of the line perpendicular to the given line
we know that
if two lines are perpendicular
then
the product of their slopes is equal to minus one
so
[tex]m1*m2=-1[/tex]
we have
[tex]m1=-\frac{3}{4}[/tex] ------> slope of the given line
Find the value of m2
[tex]m2=-1/m1[/tex]
substitute
[tex]m2=-1/(-3/4)[/tex]
[tex]m2=\frac{4}{3}[/tex]

if you flip the graph of the exponential function f(x)=2x over the x axis what is the equation of the new function
Answer:
Option: B is the correct answer.
The equation of the new function g(x) on flipping the function f(x) over the x-axis is:
[tex]g(x)=-2^x[/tex]
Step-by-step explanation:
We are given a graph of the exponential function f(x) which is represented by:
[tex]f(x)=2^x[/tex]
We know that when a graph of a function is reflected or flipped over the x-axis then the the change that take place to the function is that f(x) is transformed to -f(x).
( Since on flipping the function over the x-axis the positive value of the function get changed to negative and the negative value of the function is changed to positive)
Hence, the equation for the new function is:
[tex]g(x)=-f(x)\\\\g(x)=-2^x[/tex]
An apartment building has the following distribution of apartments: 1st floor 1 bed room 3, two bedroom 1, 3 bedroom 1, 2nd floor 1 bedroom 2, 2 bedroom 2, 3 bedroom 2, 3rd floor 1 bedroom, 2 bedroom 4, 3 bedroom 1. If an apartment is selected at random, what is the probability that it is on the 2nd floor or has 2 bedrooms
Final answer:
The probability that an apartment is on the 2nd floor or has 2 bedrooms is 0.7727 or 77.27%.
Explanation:
To find the probability that an apartment is on the 2nd floor or has 2 bedrooms, we need to determine the total number of apartments that satisfy either of the conditions.
On the 2nd floor, there are 2 apartments with 1 bedroom, 2 apartments with 2 bedrooms, and 2 apartments with 3 bedrooms. This gives us a total of 2 + 2 + 2 = 6 apartments on the 2nd floor.
Out of the total distribution of apartments, there are 3 apartments with 1 bedroom, 4 apartments with 2 bedrooms, and 4 apartments with 3 bedrooms. This gives us a total of 3 + 4 + 4 = 11 apartments with 2 bedrooms.
The probability of an apartment being on the 2nd floor or having 2 bedrooms is given by:
Probability = (Number of apartments on the 2nd floor + Number of apartments with 2 bedrooms) / Total number of apartments
Probability = (6 + 11) / (6 + 1 + 1 + 2 + 2 + 2 + 1 + 2 + 4 + 1) = 17 / 22 = 0.7727 or 77.27%
